METHODS OF DETAILED STUDY OF SEISMICITY: FORWORD, INTRODUCTION, CHAP. 1 (METODY DETALNOGO IZUCHENIYA SEISMICHNOSTI).
Abstract
The report describes the seismic apparatus used for detailed investigations. It describes new methods for the large-scale determination of the coordinates of earthquake foci worked out on the basis of experience in seismic exploration and detailed methods for the determination of the structure of the earth's crust on the basis of earthquake observations by a network of stations. Some results of these determinations are given. Methods are described for determination of seismic energy which allow for the extremely substantial influence of dissipation and absorption of energy, especially important in the epicentral zone. An analysis is given of the dependence of the dominant frequencies of oscillations during earthquakes on the dominant frequencies of oscillations during earthquakes on the seismic energy of the focus. Frequency selection apparatus is described and some of the results derived by its use are presented. The results of determination of the dynamic parameters of earthquake foci in the Garmskiy region are given with the statistical processing of the data derived. Estimates and computations are given for the parameters of earthquakes foci and displacements in foci as functions of earthquake energy.
